Description

一种生物毒性预警监测系统及其方法 技术领域
本发明涉及污水处理检测领域，尤其涉及到一种生物毒性预警监测系统及其方法。
背景技术
目前，工业和生活用水量很大，水污染问题制约着社会经济的发展。污水处理技术已从传统单纯去除污染物的高能耗、资源浪费型向污水资源化处理过渡，并开发了多种新型水处理技术。以活性污泥工艺为主要代表的污水处理工艺已经得到了广泛的应用，随着排放标准的逐渐提高，对污水处理厂的稳定运行和水质达标均提出了很高的要求。对污水处理厂进水水质的监测一般仅包含常规指标，例如常规五项、COD、氨氮、总氮和总磷等。但对于进水有毒有害物质的监测尚处于探索阶段，特别是对影响污水处理厂活性污泥的性能，造成生产事故的有毒有害物质，是污水处理厂稳定运行和水质达标需要关注并做好防范的重点之一。
水质预警系统可在污染事故发生时，对其毒性做出预先评价，对其主要污染物类型进行初步判定，并迅速采取应急措施，从而保障污水处理厂稳定运行。传统的水质监测手段主要依赖于物化分析方法，依赖复杂大型仪器设备的物化分析方法并不适用于在线水质预警系统的开发。例如，所测得的污染物浓度是水体中的总浓度，不能反映活体生物的实际暴露浓度及其生物反应，需要繁琐的样品前处理过程和专业人员操作。
生物预警技术通过生物传感器监测受试生物在不同水平上的生物学指标变化来表征水质变化实现预警。当毒性物质流入时，产电微生物活性降低，从而导致产电量下降；营养型物质流入时，产电微生物活性增加，从而导致产电量上升，通过连续测试待测样品毒性度来表示其综合毒性水平。自动控制水样导入至结果计算的全过程，实现水质综合毒性的在线监测。
